Levan Production in Shake Flask and Fermenter Influence of Feeding Strategy on Levan Yield and Molecular Weight Distribution [PDF]
Effect of feeding strategy on levan production was studied in a shake flask and a 5 L lab scale fermenter. In a shake flask, levan specific substrate yield (YP/S) increased from 0.35 g levan/g sucrose to 0.48 g levan/g sucrose with repeated batch feeding.

The molecular-weight distribution of glycosaminoglycans [PDF]
1. A rapid and sensitive method for the accurate estimation of the molecular-weight distribution of keratan sulphate and chondroitin sulphate isolated from adult bovine nasal septum and intervertebral disc is described. The method utilizes gel chromatography of reductively labelled glycosaminoglycan and end-group estimation of number-average molecular ...
